Abstract
AbstractThe emergence of antibiotic resistance genes (ARGs) as contaminants in soil poses a significant threat to public health. Earthworms (Eisenia foetida), which are common inhabitants of soil, have been extensively studied for their influence on ARGs. However, the specific impact of earthworms on penicillin‐related ARGs remains unclear. In this study, we investigate the role of earthworms in mitigating ARGs, specifically penicillin‐related ARGs, in ampicillin‐contaminated soil. Utilizing high‐throughput quantitative PCR (HT‐qPCR), we quantified a significant reduction in the relative abundance of penicillin‐related ARGs in soil treated with earthworms, showing a decrease with a p‐value of <0.01. Furthermore, high‐throughput 16S rRNA gene sequencing revealed that earthworm intervention markedly alters the microbial community structure, notably enhancing the prevalence of specific bacterial phyla such as Proteobacteria, Firmicutes, Chloroflexi, and Tenericutes. Our findings not only demonstrate the effectiveness of earthworms in reducing the environmental load of penicillin‐related ARGs but also provide insight into the alteration of microbial communities as a potential mechanism. This research contributes to our understanding of the role of earthworms in mitigating the spread of antibiotic resistance and provides valuable insights for the development of strategies to combat this global health issue.
